Coaches love to say a single play never wins or loses a game -- although don’t tell that to Nick Saban today -- but certain plays have a huge impact on the outcome. One such play occurred with a little more than 3 minutes left in the fourth quarter with Penn State clinging to a 31-24 lead over Wisconsin.

Momentum had clearly changed uniforms over the previous few minutes, as the Badgers cut a 17-point lead to a mere seven. Wisconsin was out of time outs, but it had Penn State pinned back at its 18 and facing a third and 9 after what seemed like its 50th false- start penalty of the game. A stop there and the Badgers were looking at getting the ball back, in decent field position, with about 2 minutes left.

Penn State quarterback Christian Hackenberg was working on a career-best day, so some sort of pass play was expected. But head coach Bill O'Brien pulled a surprise and sprung a draw play to running back Zach Zwinak. Zwinak hit a giant hole on the left side, thanks in large part to two good blocks, one by guard Miles Dieffenbach on Wisconsin linebacker Derek Landisch and the other by tight end Jesse James on safety Nate Hammon. On the field it looked like the parting of the Red Sea. Zwinak exploded through the opening and rumbled toward the end zone, at one point protecting the ball with two hands. He cut left heading toward the pylon, but was eventually caught by speedy safety Dezmen Southward at the Wisconsin 21.

The draw play covering 61 yards flipped the field for the Lions, essentially sealing the win. It wasn't over yet, as kicker Sam Ficken would miss a 31-yarder, but it made life a lot easier for the defense. The Badgers took over at their 21 with just 31 seconds and no time outs. A couple of Wisconsin completions and a failed Hail Mary later, Penn State was celebrating its biggest upset in recent memory.
